MACHINE_FEATURES versus DISTRO_FEATURES

The DISTRO_FEATURES and MACHINE_FEATURES variables work together to provide feasible support for the final system. When a machine supports a feature, this does not imply that the target system supports it because the distribution must provide its underlying base.

For example, if a machine supports Wi-Fi but the distribution does not, the applications used by the operating system will be built with Wi-Fi support disabled so that the outcome will be a system without Wi-Fi support. On the other hand, if the distribution provides Wi-Fi support and a machine does not, the modules and applications needed for the Wi-Fi will not be installed in images built for this machine. However, the operating system and its modules have support for Wi-Fi enabled.
